COAL-GUTTING BIAGI-TINE.

Application filed January 24,1923. Serial No. 614,571.

own power independently of a haulage ca` ble or separate truck, another object of the invention being to provide means whereby Athe machine may be brought readily into,

position for cutting or Hitting.

According to the present invention there is vprovided in a coal-cutting machine the combination of running wheels (preferably with means for throwing them into driving engagement with the machine power-shaft) with means for raising and lowering the machine relatively to the skid upon which the machine rests when cutting whereby the wheels can be brought at will into or vout from engagement with the rails or ground.

lreferably,VV the machine is hinged at one end to the skid and is provided with means (e. g., one or more jacks operating between the machine and the skid) for raising and lowering the other end relatively to said skid, the running wheels being so placed relatively to the hinge that when the machine is in its raised or cutting position the running wheels are free from engagement with the ground o-r rails on which they normally run. Y

Conveniently two pairs of running wheels are so placed that when the end of the.

machine remote from the hinge is lowered the pair of wheels nearest the hinge. will comeinto contact with the ground or railsA Figure 2 is also a side elevation of the machine but showing the position of same in its raised or cutting position, and

Figure 3 is a plan view of the front portion of the machine with parts of the casing broken away.

Like reference numerals refer to like parts throughout the drawings.

The machine is provided with two pairs. of track-wheels 5 and 6 which are arranged to run on rails 7. These two pairs of wheels are coupled by driving chains 8 working on sprocket wheels 9 which are fast with the track wheels. The aule of the rear pair of wheels 6 is provided with a bevel pinion which meshes with a bevel wheel l0 on a vertical shaft ll which carries also a spur wheel 12. The motor-shaft 13 carries at its free end a pinion 14C which meshes with a wheel l5 on a horizontal .shaft 16 carrying a worm 17. This worm meshes with a worm-wheel 18 on a vertical shaft which also carries a pinion19 engaging a pinion VE20 'gearing with the wheel l2, aforesaid.

The machine is hinged'at its forward end tothe skid 24 the hinge comprising a pair of blocks 25 depending one on each side from the machine and a pair of blocks secured tothe skid and-upstanding therefrom, each pair of blocks being joined by a pivot pin 27.

Towards the rear of the machine and situ-A ated one on each side thereof, is a pair of screw-jacks whichoperate between the top of the machine and the skid. As shown, each jack may be manually operated by means of a handle applied to the square end 29 of a'spindle carrying a worm 30 engaging a worm wheel 3l formed on the sleeve which is internally threaded for engagement with the non-rotatable screw 33. The jack is secured at its lower end to a block 34 on the skid, whereas its upper end is housed in the machine-casing.

The operation of the mechanism is as 'follows t- For cutting, the jacks are operated to raise the machine to the position shown in Figure 2 with the track-wheels clear of the rails and the whole weight of the machine supported on the skid which rests on the ground but when the machine is to be flitted the jacks are lowered to b-ring the machine into the position shown in Figure l, withthe track wheels on the rails and the skid clear of the ground. During the lowering of the machine, the front wheels will come into contact with the rails first because the wholel machine is swinging about the front hinge, and then as the lowering continues the machine will pivot about the front wheels so that the forward end of the skid will be lifted. Finally, Vthe jacks, having lowered the back wheels into contact with the rails, will lift the rear end of the skid from the ground and then the machine is free to run on theV track.

Vliat Iv claim as my invention and desire to secure by Letters Patent is 1. The combination of a coal-cutting machine, a skid hinged yat one end to said inachine to swing in a vertical plane, means for swinging the machine about said hingel relatively to thel skid and running-wheels so mounted on the machine relatively to the hinge that when the machine is in its raised engagementV with'the track onV which theyr normally run.

2. The combination of a coal-cutting ina-- chine having a motor, a skid hinged at one end to said machine to swing in a vertical' plane, means for swinging the machine about said hinge relatively to the skid, running-wheels so mounted on themachine relatively to the jhinge that when the machine is in its raised position the running-wheels are free from engagement with the track on which they normally run and means for operatively connecting said motor to said running-wheels, substantially as described.

3. The combination of a coal-cutting maf chine, a skid hingedat one end to the machine'to swing in a vertical plane, a jack operatively connected at one' end Vto said skid and at the other end to the machine, and arranged to swing the machine about said hinge relatively to the skid,jand running-wheelsso mounted on themachine relatively to the hinge that when the machine is in its raised position the runningwheels are` freefrom engagement with the track on which they; normally run, substantially as described.

4.' The combinationof a coal-cutting maf` chine having a motor, a skid for engagn ing the ground hinged at onel end to the machine to swing in a vertical plane, a jack operatively connected at one end to said skid and at the 'other' end to the maf can be raised from wheels journalled on said machine inter- "f `mediate' the ends thereof and so placedV as to form a iulcrum for the machine when the said running-wheels `are in contactwith thetrack during; appart of the swinging operation, and a second pair of running-wheels journalled on said machine in such position relatively to said lirst pair that whenthey also engage Vt-he track the skid can be raised from the ground,v substantially as described. i

6. The combination of a coalcntting machine having a motor, askid Vfor engaging/the ground hinged at one end to the, machine to swing in a vertical plane, means for swinging the machine relatively to the skid about said hinge, apair of runningwheels journ'alled on said machine intermediate tlie endsthereof and so placed to form a fiilcrum for the machine when the said running-wheels are in contact with the track during a part of the swinging opera-- tion, a second pair of running-wheels ai ranged to be driven' by said motor, journalled on said machine and so placed relatively to said first pair that wheni theyV also engage the track the skid canrbe raised from the ground, substantially as described.A

7. The combination voit a coal-cutting machine having a motor, a skid for-'engaging thek ground hinged atv one end to the -machine to swing a vertical plane, a jack operatively connected atY onerendtov said skid and at the"Y other tothe machine, and arranged to swing the machine relatively to the skid about said hinge, a pair ilo ofr runningwheels journalled onsaid ma- Y chine intermediate the ends thereof,V and so placed'as toriorm azfulcrum `forthema` chine when the vsaid running-wheels are in n' cont-act withthe track duringja part of the swinging operation, a second 4 pair olf running-wheels, arranged to 4be driven by.

said'motor, journalled on said machineand so placed` relatively to said iirst pair' that when they also engage the track theskid the ground, substantially as described. A
